Today we will take stock of how to turn waste into treasure.
The magic of cigarettes
1. It can be used as materials for computers, electric vehicles and wind turbines.
2. The materials developed by Korean scientists can be used to wrap the electrodes of supercapacitors. Supercapacitors can store a lot of electricity. Scientists point out that the material outperforms even the commercially available carbon, graphene and carbon nanotubes used to do the same job.

Bad potatoes that can't be eaten
Potato power generation mainly uses the battery made of potato and metal electrode for power supply. The working principle of potato battery is two electrodes, one side is copper, the other side is aluminum (zinc, iron are OK). Potatoes provide the acid solution needed for chemical reaction, metal zinc
When the two metals are in the acid solution at the same time, zinc will lose the electrons. These lost electrons will be transmitted to the copper sheet along the wire, forming an electric current.
